WILLIAM DEAN, OF CHICAGO, .TLEINOIS, ASSllGllTOR, BY MESITE ASSIGNMENTS,TU THE GARFORD MANUFACTUBING COMPANY, OF ELYRIA, OHIO, A CORPORATION 03useful Improvements-in Signaling Devices; and I do hereby declare thefollowing to be a full, clear,;and exact description of the invention,silch" as will enable others skilled in'th'e art to which, it ippertainsto make My invent-ion relates to signaling devices r suchas are ,mostcommonly employed upon vehicles-of varidus kinds and character andmore\"particula rly to the improvements in electrical signaling devicesof this character. In the devices of this oharacter,so far as I- amaware, constructed before my inventlon, .one'of the contactsconstituting a part of [the electric switch controlling the motor magnetand controlled by its, armature, has been mounted upon a cantaliverbeam. In this form of device, the severep'ounding of the armature willforce the free end of the beam out of position, thus changing theadjustment o the contacts. Likewise, when the beam i .removed andrestored, or when the adjust ent of the contact is made, the relation beween the two contacts will depend upon the tightness with which thescrews are inserted which hold the beam upon its support. To overcomethese objections, I mount this contact upon a bridge spanning the spacebetween two posts so that both of its ends are supported, making itimpossible for the armature to change its position, so that it will notat any time be necessary to remove the contact support, for

the purpose of re-adjustment. Thus the contacts will stay in permanentadjustment, a great advantage where devices of this character areemployed, since but few who use them are familiar with electricalapparatus.

, Another object of myinvention is to im-' prove the devices of thecharacter stated, so v that the parts can be easily reached'or readilyremoved for repairs or adjustments. For example, I mount the armaturebetween the end .of themotor and the contact carrying bridge and mountit in angular relation.

with respect to said bridge in order that it may be removed withoutremoving. the

bridge and changing the adjustment of the contact carried thereby.

Other objects of my invention and-the in vention itself will be betterunderstood by reference to the following detailed description whentakenin connection with the accompanying illustration, showing onespecific embodiment of the invention, while the scope will be moreparticularly pointed out in the appended claims.

Figure 1 is a rear end view ofa signaling device illustrating myinvention, the coverhaving been removed. Fig. A is a section takenthrough Fig. 1, showing parts of the device in elevation. Fig. 3 is adetail.

Referring now to the drawing and to the the passage of sound wavesthrough the front. A resonator 5 may be mounted in the opening .4.

The frame 1 acts as a support for the con- 'tact carrying bridge 9,which is supported therefrom, preferably by a pair of supportmg posts 7and 8, Which in the form shown pro ect from the rear of the frame,extending beyond the Walls thereof and which may be, as hereillustrated, integral with the frame. The frame also acts' as a supportfor the armature 10 which may likewise be supported from a third post 6,likewise projecting from therear of the frame, extending beyond thesame, and which may be integral with said frame. This post is preferablymounted closer to one of the posts than to the other, the bridgesupporting posts being preferably diametrically opposite one another.The magnets 11, are in the form shown, supported upon a web 12, and ananvil .13 is mounted upon the diaphragm in such relation to the armaturethat the armature may, when vibrated, pound one end of the anvil andvibrate the diaphragm, When cessful.

tact carrying bridge and firmly fastened;

two magnets are used as illustrated in the drawing, an armature longenough to span the distance between the poles of these magnets isemployed, and is connectedby a leaf spring14 to' the post 6 by suitablefastening means, such as screws 1.) and 1G.

The contact spring 17 is connected to the.

bridge 9 is attached at each end to the supporting posts .by suitablefastening means, such as screws 22 and 23, which are driven into thesupporting posts and insulated from said bridge. A cover 25 is fastenedover the rear of the signal device, covering the parts and protectingthem from dirt, etc.

As far as I am aware, the contact supporting means hitherto employed,have been defective for one reason or another, and have not properlysupported the rear contact so as to insure a permanent adjustment ofthis contact. This is a matter of some importance, since it is necessaryto make a device of this kind fool proof in order to be suc- I have,therefore, devised this coneach end of the bridge to a rigid support, sothat no amount of hammering on the part of the armature can dislodge thecontact from its normal position. I have also mounted the armature inangular relation with respect to the bridge. By this arrangement, one ofthe fastening means, 'such as the screw 16, may be removed. and thearmature swung about the screw 15 as a pivot, thus making the magnetsaccessible without removing the bridge and changing the position of thecontacts, since the armature may be moved back and the screw 16 restoredwithout changing the adjustment of either of the contacts 19 and 20. v

I have thus illustrated apparatus e nbodying my invention, though I donot wish to be limited to the details of such apparatus,

since numerous and extensive departures may be made therefrom without.departing from the scope of the invention which is set forth in theappended claims, this embodiment being shown simply for the purpose ofillustrating my invention. l
